Fix the GoHighLevel form sometimes not appearing on /contact/

form_embed.js hides each embed off-screen until the iframe reports ready.
With loading="lazy" the hidden iframe often never loaded, so it never
reported ready and the form stayed invisible. Load the form eagerly, reserve
its height, and reveal any embed still hidden after a few seconds.
